Sinister Diesel LBZ EGR Delete

2006-2007 Duramax (LBZ)


Ready to stop sending exhaust and soot through the intake side of your engine? Sinister Diesel’s EGR delete for the LBZ Duramax gets rid of both the EGR valve and EGR cooler. As a result, performance-hindering soot and carbon buildup will no longer accumulate in the engine’s intake tract and cylinder heads, and the engine coolant leads a much easier life. Quicker spool up and lower EGT can be observed after installation. Improved long-term engine reliability is the core benefit of installing this kit.



  • *Billet-aluminum EGR block-off plates with O-rings
  • *Nickel-plated steel exhaust block-off
  • *Stainless steel support bracket
  • *Hose clamps and all hardware included
  • *Removal of turbo, up-pipe, or intake manifold is not required


*Offroad Modification Only: Not legal for use on the street in any pollution controlled vehicle in the United States.


Customer Reviews

Nice fit and finish Review by Brian
This kit went together really well. I would recommend the Sinister kit, it fits nicely with no prying or misalignment at all. (Posted on 5/5/2015)
